Fastener folders are made of extremely durable, 25 point pressboard covers to withstand heavy use. 2" embedded fasteners in positions No. 1 and 3 on the covers keep documents secure and allow subdividing within folders. Also use the fasteners to keep documents in sequential order. Tyvek tape spine expands with your projects. Standard-size top tabs with an undercut score on the front cover provide room for labels or handwritten titles. Tabs are 1/3-cut in assorted positions for easy organizing and file identification. Fastener folders also offer a high percentage of recycled material.
